AIR STRAINER FOR HEATING UNITS.

Application filed January 11, 1927. Serial No. 160,430.

The invention relates to air strainers foiheating units, such asradiators, registers or stoves for heating rooms, and has for its objectto provide a device of this character adapte-d to be placed in closeproximity to the heating unit and provided with a cham'- ber in whichscreening material, such as metal wool, is placed and through which airpasses in its movement adjacent to the heating unit in being heated,thereby separating the dust and dirt from the air and thus preventingthe deposit of dirt on the walls, ceiling and other objects in the room.

A further object is to provide means adliacent to the air strainer, suchas metal anges, which will cause air that circulates vin'proximity tothe heating unit, such as a radiator, a register or -a stove, to passthrough the air strainer and thereby remove the dust and dirt from theair as it is being circulated and heated in the room.

A further object ,is to provide the airv strainer with a removableapertured cover forming a closure for the screening materialcompartment, thereby allowing access to the screening .material forrenewal or cleaning purposes.

A further object is to provide the bottom of the screening materialcompartment with 'a screen preferably made from` wire mesh materialthrough which the air may pass to the screening material.

A further object is to provide, in combination with an Yair strainer forheating units, a fluid container for disinfecting theair or increasingthe moisture in the air of the room in which the heating unit is placed.

With the above and other objects in view the invention resides in thecombination and 0 arrangement of parts as hereinafter set forth, shownin the drawing, described and claimed, it being understood that changesin the precise embodiment of the invention may Y be made within thescope of what is claimed without depart-ing from the spirit of theinvention. Figure 1 is a view in elevation of a conventional form ofradiator supported vfrom the floor showing the air Astrainer appliedthereto on the sidelof the radiator in combination with a deiiector. ,oFigure 2 is a vertical transverse section taken -on line 2-2 of Figure1.

Figure 3 is a view in elevation of a radi? ator supported from the Hoorshowing the ait-r strainer applied tothe top of the radia or.

Figure 4 is a vertical transverse section taken on line 4-4 of .Figure3.

Figure 5 is a View in elevation of a conventional form of radiatorattached to the wall of the room showing the air strainer applied to thetop, front and ends of the radiator,

and l Figure 6 is a vertical transverse sectional view taken on a line6-.6 of Figure 5. Referring to Figures 1 and 2 of the drawr ings thenumeral 2O designates a heating unitsuch as a conventional form ofradiator supported from the floor which may be any type and on which airstrainer is removably located by supports 21. The air strainer showninFigures 1 and 2 comprise perforated members 22 and 23 which areconnected together with top and bottom plates 24 and 25 and in which isdiposed the screening material 26` such as steel wool. The casing formedby the members 22, 23, 24 and 25 35 and a detachable perforated covering36.

Disposed inside of the casing is the straining material V37, such assteel wool, anda fluid receptacle 38. The fluid receptacle 38 is areceptacle for holding fluid or other substance forsterilizing orhumidifying the atmosphere of the room.' v

Referringto Figures 5 and 6, the radiator 61 is supported from the wall62 by brackets 61a. the radiator 61 and is constructed similar to theair strainer shown in Figures 3 and 4. In addition to the air strainer64, the' nur inerals65 and 66 designate side and end air strainers. Theside air strainer 65 depends at an angle from the air strainer 64 andthe air strainer 66 depends from the ends of the An air strainer 64 issuperimposed above,

strainer 64. The air strainers 65 and 66 are v constructed similar tothe air strainer 64 having a lperforated casing'containing air strainingmaterial 68, Fig. 6, such as Vsteelv wool. 4

The principle on which the airv strainer opera-tes' is that the cool airin the room-circulates near the oor and Yis drawn towards `thehea-tingunitzand'n moving towards the "so thatthey willvreadily stick"tothe walls," 'ceiling and other objects in therroom while*v still warmand lwhen these particles cool off heating 'unit picks up the fineparticles of j dirt and dust andcarries them into` the rad-i.

ating area. ofthe heater.'1 `These particlesfof dirt and' dust,v`whenheated, become pliable the remain wherethey have been deposited anfastened to the w'*a.11s,ceiling and other objects in thereom. v

From. the foregoingitwill lhe's'een. that 4an f air screen' for aheating unit is -privided `that lair that circulates in close 'to theheating `unit.wil1 pass` t rough a screening material.- therebyseparating. the

which may be easily andquickly applied to a conventional .form,ofradiator, register,
